CUCHION-OOVER CONSTRUCTION.

Application filed July 18, 1925. Serial No. 44,416.

To all whom it may concern:

Be it known that I, SAMUEL SUnKorF, a citizen of the United States of America, and a resident of Chicago, in the county'of Cook and State of Illinois, have invented a certain new and useful Improvement in Cushion- Cover Constructions, of which the following is a specification.

This invention relates to improvements in spring cushion construction, and more particularly to an efficient and economical method of fabricating and assembling cushion covers adapted for use with resilient filling units such assprings or cusl'iioning material.

As commonly made, a cushion cover consists of pieces of fabric usually burlap, cut andsewntogether not only to form the bottom, top and side walls, but a series ofindividual cells or pockets within the outer walls and adapted to contain the resilient material units. The problem of making cushion covers is not merely one of structure, but it is one of method of preparing the material for sewing, and then sewing the pieces together, sothat the cushion can be loaded with resilient material withthe least amount of time and labor. 1. 3

The object of the present. invention is, therefore, to provide a method of further reducing the labor cost of cushion construction, attention being called to the fact that inthe present highly competitive state of the cushion industry, an unprofitable business may become profitable by an apparently inconsequential saving in the item of labor costs. Thus, the elimination in one step of the manufacturing process, or the completion of two steps in a single operation, or a more efficient treatment of the material in preparation for assembling, would be important to the manufacturer in meeting competition.

Of. such a nature is the present invention and its applicability to the art will be bet ter appreciated as the process is disclosed with the aid of the accompanying drawings, i 1 1 w h ich. I

. Figure 1 is a perspective view showing a portion of the material forming one of the covers, said material being marked off for subsequent sewing of partition strips along predetermined lines.

Figure 2 is a similar view of the piece shown in Figure 1 but illustrating the arangement of two sets of partition strips as applied thereto to form a base.

Figure 3 is a fragmentary view of a top cover with partition walls in place ready to be attached to the bottom piece shown in Figure 2.

Figure I is a detail view in vertical sec- -tion showing the top and bottom members part ally JOIDGtl together in the process of in a seam 3 extending around the cushion between the top and bottom thereof, the marginal portions of these pieces forming a f boxing, or endand side walls of the cushion.

Within the outer covering formed by the pieces 1 and 2 are a series of continuous partition strips 4 extending the full length (or width) of the cushion with the longitudinal edges sewn to the top and bottom cover pieces. These partition strips are parallel with each other and divide the interior space of the cushion into a plurality of full length compartments.

In. connection with the compartments formed between the partition strips I and between the outer of said strips and the parallel end (or side) walls of the covers are provided a plurality of division walls 5 which divide the cushion into a plurality of maller compartments or cells. In thefinally completed cushion, each of these division walls 5 is made up of two parts 5-5 sewn together adjacent their center on a seam 5 as will hereinafter appear. Each set of tabs 55 is made up in two sets of oppositely disposed strips or combs indicated generally by numerals T and S, as shown separately in Figure 6, the lower strips or combs I being attached to the bottom cover 2 as shown in l igure while the upper strips or combsB are attached to the upper cover 1, as shown in Figure 3. The'va-rious steps taken in constructing the complete cushion cover will now be described. i

The first step in the process is to providea pair of similar top and bottom pieces 1 and 2having sewing lines. l0 arranged at right angles to each other, to outline the size of the compartments or cells of the complete cushion. To one of these pieces of material, as for instance the bottom piece 2 as shown in Figure 2, is secured a comb 7, shown in Figure 6. This comb is cut from a" single piece having a series ofnotches or cuts 5 formed therein and extending almost to the base 7* to form tabs 5 this base being of sufficient width, however, to permit the comb to be secured to the cover 2 along a seam 12 which follows one set of thesewing lines lOQthereon. The arrangement is such that when thus secured to the base 2,

' the bottom margins of slots 5 5 reach substantially to the bottom cover 2, as shown in Figure 2. An entire series of strips 7 are arranged in parallel relation along adjacent sewing 1111 10 10011 the base 2 and thereafter a'plurality of transversely disposed partition strips 4 are also secured to the cover 2 along scams 4?, these seams following transverse sewinglines 10 and passing through thealigned notches 55 as shown in. Figure 2. Asin-dicated in dotted lines in this figure, it will be seen thepartition 4 issubstantially twice as high or wide as the combs 7 Referring now tothe top piece 1, a plurality of combs 8 of construction similar to combs? shown in Figure 6, are arranged along parallel'seams 13 to correspond with the similar combs? secured to the bottom cover The arrangement is such that the top cover 1 with its combs 8 assembledthereon may be fitted over the bottom cover 2 with its combs 7 and partitions 4 inpositiontobe secured together in finally assembled form, as shown in Figures 4 and 5. i The preferred method of securing these partsm-ay be described as follows:

Starting along.v one edge of the cushion parallel with the partition strips 4, the cells or compartments are completed pro gressively in rows toward the opposite edge of the cushion substantially as follows: The first row of tabs 5? 5'- of the abutting combs? and 8 between the. first partition strip 4 and the cushion edge are sewn together along seams 5 The free upper edge of the first partition 4 is then inserted in corresponding notches?) and sewn to the upper piece 1 along a seam 4 as'shown in Figure 4', this sewingoperation being continuous throughout the entire length of the,

partition 4 to completethe first row of compartments between the first partition 4 and the adjacent end wall. The assembling operation may then be continued as follows: The second row of pairs of abutting tabs -5 adjacent the first partition strip 4 are joined along seams 5", and then the second partition strip 4 is sewn to the top cover 1, to complete the second row of compartments. This. operation is then repeated until all the compartments are formed. One or more of the side and end walls may be closed or boxed along seams 3 at anytime in the process, although, of course, the cushion is not finally closed. or boxed along all sides untilthe individual compartments are loaded with suitable re? silient material, as will herein-after be de:

scribed. I i p Oneof the principal advantages of the construction above vdescribed is'theprovisi0nofthe combs 7 and 8 and the partitions 4 in such, a manner that they may each be, con F1 v the part of the cover already assembled, and V 7 may thus be quickly sewn together along the seam 5".

further advantage of the construction described is that the sides of the partitions 5 are loose, that is to say,they are not .u

joined along their side marginsto the partition 4, in thepreferred form shown, being spaced slightly on opppsite. sides of each partition 4, thus permitting the flexibility that is essential to rapid and convenient loading, of the cushion with resilient material.

The, cushion described is particularly adapted forv use with resilient springs com prising helical coils of wire, whichsprings may be inserted, through the loose side of each row of compartments. As a preferred method of loading the cushion with: springs, an implement known as a loading tool is used in which a'number of springs equivalent;- to the number constituting a single row, are held flatly compressedwithin the tool. The tool is then inserted intothe open, endof the cushion and along one side of each longitudinal compartment formed between suecessive partition strips 4, the tool. being held so that the flattened springs pass through the openings between the partition strips and the adjacent edges of the tabs. It will be understood, however, that a cushion cover constructed in accordance with my invention may also be loaded with other resilient cushioning means. i

As before explained, the process of assembling the cushion cover from corresponding combs 7 and 8 and transverse partitions 4:, results in a marked saving of time, labor and material in the manufacture of the cover, eliminating the sewing of a multitude of short seams, each of which may be a separate sewing operation.

I claim as my invention:

1. A cushion cover construction comprising top and bottom cover pieces, a plurality of para-llelly disposed combs each consisting of a single piece of material sewn to said cover pieces along one edge and provided with spaced cuts extending from the free outer edge substantially down to said sewn edge, a plurality of partition strips arranged transversely of said combs and sewn to said cover pieces along lines passing through aligned cut portions of said combs, said combs being slightly more than one-half the height of the completed cushion and sewn together along their abutting edges.

2. A spring cushion container comprising 7 top and bottom pieces of cover material, parallel and oppositely disposed combs sewn along thelr connecting edges to each of said pieces of cover material and iewn together at their adjacent registering edges, and partition strips constituting a continuous piece of material substantially twice the height of said combs sewn to each of said cover pieces on lines extending at right angles to said combs and passing through aligned rows of cuts therein.

3. A cushion cover construction comprising top and bottom cover pieces, a plurality of parallelly disposed combs each consisting of a single piece of material sewn to said cover pieces along one edge and provided with spaced cuts extending from the free outer edge substantially down to said sewn edge, a plurality of partition strips arranged transversely of said combs and sewn to said cover pieces along lines passing through aligned cut portions of said combs, each abutting pair of combs having aggregate height slightly more than the height of the completed cushion and being sewn together along their abutting marginal edges.
